It seems to me that the preponderance of these examples shown have a fairly strong Western European stylistic influence; many having a sort of Hirschfanger-like appearance to their hilts .
I would be most interested to see stylistic examples that could be attributed to pre-VOC times .
I'm a bit skeptical about these weapons being at all a native concept; rather I think one could posit that they were made (and quite well in many cases) solely for the eyes (and purses) of the Dutch .
I am led to understand that the town of Tjikeroeh aka Cikeroeh(sp?) is the modern day location of some of the best (air) gunsmiths in Jawa .
